Procedure

A mixture of (E)-3-[6-(2,5-dioxo-pyrrolidin-1-yl)pyridin-3-yl]-N-methyl-N-(1-methyl-1H-indol-2-ylmethyl)acrylamide (260 mg, 0.645 mmol) and ammonia (12 mL of 0.5M solution in 1,4-dioxane, 6.0 mmol) in a sealed tube was heated to 60° C. overnight. After cooling to ambient temperature, the resulting white precipitate was collected by filtration. The resulting solid was triturated with MeOH, washed with Et2O, and dried under high vacuum at 50° C. for 2 d to give the title compound (140 mg, 52%) as a white solid and as a mixture of amide rotamers: mp 225-227° C.; 1H NMR (300 MHz, DMSO-d6) δ 10.67-10.63 (m, 1H), 8.62-8.58 (m, 1H), 8.21-8.07 (m, 2H), 7.60-7.25 (m, 5H), 7.12 (dd, J=7.7, 7.4 Hz, 1H), 7.00 (dd, J=7.3, 6.9 Hz, 1H), 6.77 (br s, 1H), 6.42-6.17 (m, 1H), 5.05-4.85 (m, 2H), 3.72-3.68 (m, 3H), 3.12-2.99 (m, 3H), 2.64-2.60 (m, 2H), 2.40-2.36 (m, 2H); MS (ESI) m/e 420 (M+H)+.
